DOOR-CORE-ASSEIVIBLING DEVICE.

Application filed August 30, 1922. Serial No. 585,157.

T all whom it may concern:

Be it known that I, EDWARD Sarzcnn, Sn, a citizen of the United States, and resident of Cincinnati, State of Ohio, and county of Hamilton, have invented certain new and useful Improvements in Door-Co-re-Assembling Devices, of which the following is a full, clear, and exact description, reference being had to the drawings accompanying this specification.

My invention relates to machines on which 7 the cores used in veneer finished doors, are made up from different length pieces of wood, united by glue into a solid core or strip of suitable dimensions to form the framework parts of the door, as distin: guished from the panels.

In the construction of veneer doors, the frame work parts are customarily formed of two strips of wood of the width of the edge of the door to be made, and of the desired dimension lengthwise of the door, or across the top or bottom thereof. Between these strips are assembled small blocks of wood in staggered relation as in brick-work,

to full up, together with the two full length strips, a core of a'size to give the desired width to the frame work part. The two full length strips and the smaller blocks filled in between them are cemented and clamped together and when dry are used as door frame parts, with the veneerplaced over, the edgewise portions of the various wood pieces.

This operation, while a great saving in wood, requires, according to present processes, that the workmen assembling the pieces, have to carry them to another point for cementing. I am aware of no mechanical device designed to facilitate this work, prior to my invention herein.

It is thus the object of my invention to provide a device on which the various wood pieces can be assembled at one point, then mechanically moved to .another point where the clamps are placed on them, without disturbing the positions of the pieces. It is also my object to construct a machine for doing this work which will be as simple as possible, and yet be effective.

For one thing the work to be done involves the presence of a great deal of glue, andmy mechanism is designed for the purpose of" being easily cleaned.

I accomplish my objects by that certain construction and arrangement of parts to be hereinafter more specifically pointed out v and claimed.

In the drawings,

Figure 1 is a perspective view of one of my machines in operation.

Figure 2 is a detail perspective of a veneer door frame piece, with the veneer broken away in part.

Figure 3 is a clamp.

Figure 4 is a side elevation of the clamp, showing a section of the built up door. frame piece.

Figure 5 is a detail side elevation of one of the reel arms. c

1 Figure 6 is a like viewshowing a reel arm formed of a piece of iron pipe or the like.

Referring first to the door body p which it is desired to make I have shown the built up board ready for veneerin Figure 1 and a portion of a door in F igure3. In these two views, 1, 1, indicates the facing perspective view of the art I boards, of the-huiltup structure. Theseas heretofore stated are of a. width to equal the desired thickness of the door, one of the pieces serving as the edge 2, of a complete door, without veneer. Between the pieces 1, 1, are laid a series "of small blocks 3 of what ever wood is desired, these blocksbeing cut of uniform thickness of each row, and arranged in different lengths so that a staggered relation can be preserved in arranging them.' I/Vhenglued together, one of these pieces may be used, for example in -forming the panel frame of a door, with the edgewise portion of all pieces exceptat the top and bottom, covered with veneer 4;.

The clampsemployed with my device are not of my invention'but have long been in use. They comprise. U-shaped body portions 0, having a series of holes therein for the reception of a stop pin 6. On a threaded shaft 7, is mounted a follower block 8, and the shaft is set into the threaded-sleeve 9 formed'at the juncture of the" clamp arms tion, I provide a machine having four corner posts 10, and front top bar 11, and two side bars l2, 12. As an additional support I provide a series of interspaced upright boards 18, located under the reel portion of the device (to be described), these boards being joined together at the lower end, by a board 14:, and the base boards 15 along the lower ends of the standards.

Mounted securely in a horizontal position, edgewise, on the front top bar 11, and se cured to the interspaced uprights 13, are a series of iuterspaced boards 16, making up the table of the device. 4

Set on suitable journal blocks 17, at the rear ends of the machine, behind the ends of the boards 16, is a reel shaft 18, having a handle 19. This shaft has series of interspaced arms 20 thereon. As shown in Figure 5 the arms are of wood and secured to blocks 21, which are fixed to the shaft. As shown in Figure 6 the arms are of a piece of pipe 22, bent around the shaft and bolted or riveted thereto.

In either case, each arm carries a bracket or support 23, extending laterally from the arm.

The arms are so set on the reel shaft, that when the shaft is revolved they will pass down between the interspaced table boards, and the interspa-ced uprights. The supporting brackets on the arms act as a shelf on .which to assemble the composite board.

I have shown the reel as equipped with one set of arms only, but this might be duplicated.

In use when the device is in the position shown in Figure 1 the operator places one of the facing boards of the composite structure on the brackets at the rear of the arms, and piles up the small blocks, using suitable wood glue between all pieces. He finally places the top board onto the pile, when he has gained the proper thickness of the built up blocks, and revolves the reel.

The result of this is to hold the assembled pieces on the arms and brackets, until the arms have come to the level of the tops of the interspaced table boards. The reel is so set that this will occur, so that the glued together bundle is deposited on the table, without destroying its shape in any way. Another operator will then slide a clamp in between selected boards of the table so that it straddles the pile, and drops a pin in place after which he screws up the follower. Two clamps should serve for the ordinary composite board, and after clamping tightly the clamped bundle is set aside to dry.

While the clamping is being done the first operator starts another built up structure on the arms, which will have been turned around to starting position after depositing the bundle.

The operation of the machine is very simple and acts to convey the bundle from one point to another safely and to hold it while being clamped.

The spacing of the table boards will be arranged to suit the width of the metal of the clamps.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. In a device of the character described, a table formed of interspaced members, and a reel having interspaced arms thereon, set so as to pass between said members substantially for their full length and means for supporting the table members without interfering with. the complete revolution of the reel, said interspaced arms having members thereon constituting lateral supports for a composite board structure at right angles to the arms.

2. In a device of the character described, corner standards, front and side boards at the upper ends of the standards, interspaced upright supports, secured adjacent the lower ends of the standards and toward the rear of the device. interspaced table forming boards secured to the front board mentioned and individually secured to corresponding ones of the interspaced upright supports, a shaft mounted across the device and at the rear thereof beyond and substantially at the level of the table boards, and a series of arms mounted in parallel with each other on the reel, said arms being so interspaced as to pass between the table boards and upright supports, substantially for their full length. i

3. In a device of the character described a work supporting table formed of interspaced boards, having sufiicient space between them to permit of the edgewise insertion of a veneer-door board clamp, a reel with interspaced arms having horizontal supporting members adapted to support a built up veneer-door board on its side, while same is being formed, said interspaced arms adapted to pass between the table boards substantially their full length to deposit the built up board edgewise on the table.
